(Superseding IS 12748 : 1989)

Reaffirmed 2022

NATIONAL FOREWORD

This Indian Standard which is identical with ISO 18906 : 2000 ‘Imaging materials - Photographic films - Specifications for safety film’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Photography and Cinematography Equipment Sectional Committee and approval of the Mechanical Engineering Division Council.

This standard was earlier published as IS 12748 : 1989 ‘Cinematography - Motion picture safety film - Specification’, based on ISO/DIS 543 : 1974 ‘Cinematography - Motion picture safety film - Definition, testing and marking’. As ISO 543 has been revised and replaced by ISO 18906 : 2000.

The committee has now decided adopt ISO 18906 : 2000 in a single number series as IS/ISO to make pace with the latest international practices.

The standard supersedes IS 12748 : 1989 and after the publication of this standard IS 12748 : 1989 shall be treated as withdrawn.

The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
